Under free vibrations and damped conditions, a SDOF portal frame fixed at its base has a mass of 1,500 kg at roof level. Lateral stiffness of frame columns 1 and 2 are: k1 = 12,500 N/m, and k2 = 13,500 N/m. Viscous damping coefficient is 435 N s/m. Find: 1.) the natural period of oscillations 2.) cyclic natural frequencies 3.) circular natural frequencies 4.) If the initial displacement and velocity are 20 mm and 23 mm/s, compute frame side sway after 1.5 s.
